11 Claims.

The present invention relates to an automobile parking facility and more particularly to a device of the type in which automobiles may be stored or parked in vertical tiers, thereby taking-maximum advantage of available ground space in congested areas.

An objectof my invention is to provide an automobile parking device by which a plurality of automobiles can be conveniently handled and parked with a minimum of ground space requirement.

Another object of the invention is to provide a parking facility having a plurality of flights or lifts upon each `of which an automobile may be parked and maneuvered up and down with respect to a single elevator drivemechanism.

A further object of `the nventionpis to provide a columnar type of automobile storing and parking device in which parked automobilesmay be arranged upon iiights or vlifts 'in an ascending manner at one side ,of supporting column and turned about at the upper end of the column, then lowered downwardlyalong the other side of said column for dischargeV therefrom.

Another object of the invention is to provide a novel type of drivefor an automobile parking device of the character described in;which the vertical vand transitional ,movements of the automobile supporting lifts or flights are synchronized and driven by a single common sourceiof'power.

Another objectk ofthe invention'is toprovide a novel type of drive for, an automobile parking device of the character described in which the vertical and transitional movementsfof the automobile supporting lifts or flights Voperate in timed relation and are driven by a common source of power. Y

Another object ofthe invention is to-provide'a columnar type of automobile-parking device having a novel arrangement of turnable'trackways at `both its base and upper end which will permit a transfer of automobilesupporting iiights or lifts from one side of the supporting column to the other side thereof and wherein a single elevating mechanism is employed for controlling the position and movements of usaid flights or lifts in both their ascending and 'descending movements and in their turning `movement with respect to the sup-porting column.

Other objects and advantages ywill-loe in part evident to those skilled inrthearty and lin part pointed out hereinafter inv connectionwith theaccompanying drawings wherein there is. shown by way of illustrationand. not.` of limitation a preferred embodiment of the invention.

Figure 10 is a view takenralong lines X-KX of Figure 9 showing the detailsY thereof. y

Upon referring particularly to Figures 1,V 2 and 3 ofthe drawings it will be seen that my improved parking device is of the type upon-which a plurality of automobiles can be parked in tiers one above the other over a ground area slightly greater than that which would be required for parking two automobiles side by side on the surface of a parking lot. In the embodiment here shown the device is adapted to accommodate six individual automobiles butJ it is to beunderstoodthe device may be extended vertically to any reasonable height in order to accommodate eight, ten or more automobiles arranged in double tiers without departing from the spirit of the invention.

In brief outline and as shown in these figures of the drawings the invention comprisesicolumnar type of support composed of two main supporting frame members IU and II that are spaced with respect to each other. These frame members I0 and I I are connected at their top Aby a head portion I2 which extend from the frame member IIJ over and above the frame member II. At their lower ends the frame membersI .and II are secured to a baseportion I3 which `may be of any suitable conguration. In vthe drawings the base portion |73 is shown in the form of two right angled frame forming members I 4 and I5 that are disposed at right angles to each other and eX- tend outwardly a distance sufficient to form a firm foundation for the columnar forming frame members III and II. The frame member II is of channel like configuration in cross section and mounted upon its channeled side there are two double sprockets I3 and I'I' that carry a sprocket chain I8 which, as will hereinafter appear, operate as a means for elevating a plurality of automobile supporting platforms or lifts I3 to 24 inclusive.

As more clearly shown in Figure 2 of the drawings, the automobile supporting platforms or lifts I9 to 2L;l are of a cantilever type. These lifts are each carried by two spaced upwardly and angularly extending struts or bracket arms, designated respectively by the numerals 25 to 30. As will be pointed out in more detail hereinafter, these struts or bracket arms 25 to 33 are pro vided with anti-friction or roller means 3i and 32 which engage with vertically extending rails or guides 33 disposed in pairs forming vertical trackways at opposite sides of the column forming members IG and I I. In addition to the rollers 3l and 32 each of the struts or bracket arms 25 to 33 also support an extending dog or abutment 34 which projects inwardly to a point where they will engage with extending pintles or dog engaging arms 35 that are arranged in spaced relation along the length of the sprocket chains I8. In this manner, as shown in Fig. 2, the sprocket chains I8 will operate to move the flights or lift platforms I9, 2G and 2I upwardly along the spaced rails 33 at one side of the column formed by the frame members I and I I while the flights or lift platforms 22, 23 and 24 will move downwardly along the spaced rails 33 at the other side of the column.

A novel feature of the invention resides in the provision of extensions of the track ways formed by the rails 33. One of these extensions located at the upper end of the rails 33 is formed by similar rails 36 which are carried by and depend from a bull ring 31. This bull ring 31 is journaled upon the head portion I2 and the rails 33 are disposed in alignment with the rails 33. When the rails 36 are in the position illustrated it will be seen that the uppermost of the flights or lift platforms will be supported thereby while the dog or abutment 34 is maintained in Contact with the pintle or dog engaging arm 35 upon the sprocket chains I8 as it passes over the sprocket It. At the base of the column formed by the members Il] and II there is a similar arrangement of spaced rails 3B that provide an extension at the lower end of the track ways formed by the rails 33. These spaced rails 3B are carried by a second bull ring 39 which is journaled upon the base formed by the members I4 and I5.

By now referring back to Figure 1 of the drawings it will be seen that the bull rings 3'! and 33 are each provided with teeth about their periphery which form gears lil and 4I. The gear 43 carried by the bull ring 3l is shown as driven by gear 42 carried by a shaft 43 which is adapted to be driven in an intermittent manner or in timed relation with the sprocket chains I8. In this manner, when one or the other of the lifts I3 to 24 are moved upwardly and into full support by the downwardly extending spaced rails 33 carried by the bull ring 31 it may be moved, as will hereinafter appear, from one to the other side of the column. In like manner the gear 4I is shown as adapted to be driven by a gear ill carried by a shaft 45 which is also arranged and adapted to be operated in an intermittent man- 4 ner in synchronized relation with movements of the platforms or ilights I9 to 24 vwhen they reach their lowermost position and in full engagement with the upwardly extending spaced rails 38 carried by the bull ring 39.

As more clearly shown in Figure 3 of the drawing, the lift platforms or flights I3 to 23 inclusive are of rectangular outline and have a total horizontal area slightly larger than the overall dimensions of the largest automobile which might be placed thereupon. As a means for positioning an automobile substantially centrally thereupon and preventing any possibility of an automobile rolling therefrom without set brakes, the lift platforms or flights I3 to 23 each have spaced runways 46 and 4I with a waved or uneven tread surface. Such a surface is provided by elevated transversely extending ridges 48 and 69 adjacent the ends of the platform and depressed portions or valleys 50 and 5I that are positioned at points which will correspond with the spacings of wheels of the average automobile. With this arrangement it will be seen that where the valleys 50 and 5I do not correspond exactly with the spacing of wheels of an automobile at least one of the sets of wheels will settle in one of the valleys 50 or 5I. Another feature of these flights or lift platforms is the provision of an under plate 52 which acts as a canopy to prevent grease or oil dripping from one automobile to another when parked upon one of the lift platforms or ights I9 to 24.

In Figure 5 of the drawings there is shown in more detail how the platforms or flights I3 to 2li inclusive are supported for movement along the rails 33 and the extensions 36 and 33 by the sprocket chain I8. As here shown the spaced rails 33 and the extensions 36 and 33 are formed of angle iron and. are disposed so that one of the flanges thereof, designated by the numeral 53, extends outwardly and in alignment to provide continuous and oppositely exposed surfaces along which the anti-friction means or rollers 3I and 32 will move. The rollers 3l are mounted at the lower ends of the platform securing brackets 25-30 and the rollers 32 are shown as mounted at the upperend of these brackets. In this way the rollers 3l function as a fulcrum over which the projecting platform or flights I9-24 are supported in cantilever fashion by the rollers 32, at the upper end of the brackets 25--3IL which engage with the inner surface of the flanges 53 of the rails 33, 36 and 38. It will be understood that these platform supporting brackets may be constructed in a number of dii ferent ways. In the drawing the brackets 25--33 are shown as composed of two spaced upwardly and angularly inclined members that are secured together in spaced relation by transversely extending angle irons 54 and 55 which are preferably welded in place. The dogs or abutments 34 carried by these brackets are formed by an extension upon vertically disposed plate members 56 that are positioned between and welded to the angle irons 54 and 55. The spaced rails 33, 36 and 38 are also secured in spaced parallel relation by means of tie plates 51 that extend horizontally therebetween.

By now referring to Figure 6 of the drawings it will be seen that the bull ring 39 at the base of the supporting column, is journaled or supported for rotation upon a plurality of radially disposed rollers 58 that are mounted upon stub shafts 59 carried by an annular or ring supporting member 60 which is secured .to the base formed bythe right angle members Hand I5.

It will be-noted here that the vertically extending frame member I I is disposed at one side of the center of the Aannular or ring like member 60 and serves with the latter member as a support for a horizontally extending stub shaft Si that carries the lower double sprocket Ail about which the double sprocket-chain I8 passes. In this instance, a bushing 62 provides a bearing for the stub shaft 6I. At the left of this View there is shown the rmanner in which the gear 4I operates with the gear teeth te carried by the bull ring 39. The frame forming member II, referred to above, as disposed at one side of the center of the annular column or supporting ring 60, carriesthe sprockets IS and Il iny such a position that'the extending pintles or abutment engaging dogs 35 carried by the chain I8 will extend over and/or through a vertical plane extending at a right angle to the plane of the trackways formed by the spaced rails 33, .'55 and 38. In this figure of the drawing the abutment or dog engaging pintle 35 is broken away Vand the dog or abutment 3i with which the pintle 35 engages is only partially shownto illus trate the relative positions of these parts when the associated platform orlift i-Zil is in its lowermost position and midway its transitional movement between the descending and the ascending side of the supporting'column formed by the members I0 and II. The novelty of this arrangement is that lthe extending pintle or `abutment engaging dog 35'carried by the chain is always in a position where it will be engaged by the dog lor abutment Mcarried bythe platform securing brackets --30 as these brackets, together with the platforms |9-2i, are moved from one side of the column or support to the other at the ends of their paths of vertical travel.

Figures 7 and 8 of the drawings diagram matically illustrate the above described feature. While these illustrations are limited to condi tions at the lower sprocket I1 with the lower most platform or lift supported by the spaced rails 38, it will be understod that a corresponding action will-take place at'the upper sprocket it when a bracket with its supported platform' reaches its uppermost point vof travel and'into full support by the spaced rails St carried` by` the bull ring 37. In these figures the sprocketchain It is shown with its dog engaging' pintle 35 and the dog or abutment 3d in the Adifferent relative positions which these members'vvill assume' in. their movement about the sprocket l l. By Ycoinparing the positions of the abutments Sli `With respect to the pintle 35, as illustrated in Figure 8, it will be noted that the dogs 3s of theA respective platforms will'remain in overlapping relation with a supporting pintle vat all times during its travel from one to the other side Yof the sprocket I. In this showing when the abutment or dog 34 is in position Af the particular platform supported thereby will be in its descending movement. This engagement vwill then continue during this final downward movement through the positions B and C. VWhen the platform or lift has reached its .lowermost position the dog or abutment 3e will be in substantial alignment with the axis of the pintle 35. As shown the length ofthe pintle 35 is. such that it will extend over thek center line'of the column and will therefore continue as a support for the dog or abutment 34 carried by `thebracket Vzontal platform ed.

While the supported .platform'continues .in its transitional clock-wise movement. From this point the dog or abutment carried by the bracket will move in an upwardlydirection through the positions E, F and G, where in this latter position the platform will be in alignment for upward vertical travelalong the rails 33 at the other side of the supporting column.

The reason for the employment of the Ydouble sprockets I1 and I 8 together with two similar sprocket chains I8 which operate in unison will now be apparent. It will be evident that a single sprocket chain I8 would be incapable of supporting the extending pintle 35 in such manner as to carry the weight of a platform in the manner explained. The employment of two, spaced sprocket chains upon the double sprockets il' and I3 is a requirement in order to obtain the supporting function performed by the pintle 35 as the platforms are moved from one side of the column to the otherat the upper and lower ends of the platform supporting column. There fore, Where reference is made to the sprocket chain I8 it will be understood that the double chain arrangement as here shown is intended. It is however conceivable that a link belt type of chain having suicient width might be substituted if conditions should warrant such a change.

Reference is now made to Figures 9 and l0 of the drawings for a description of the drive provided for the sprocket chains It and the rotary or transitional movement of the trackway eX- tensions formed by the rails 36 and 33 respectively at the top and bottom of the platform supporting column. As here shown the supporting member it carries a gear housing 53 within which there is enclosed a set of gears 6d, E35 55 that are disposed and suitably supported in vertical alignment by the frame member iii. The gear B is arranged to be driven by an electric motor 6'! mounted upon a bracket et? that is part of the housing 63. The intermediate @E is mounted upon a stub shaft 6i@ and the gel 1` E5 is keyedupon a horizontally extending shart le which carries the upper double sprocket i5. At this end the shaft l@ is journaled in a bearing 'H carried by the frame member i i. As .h shown the intermediate gear S5 has a pla or disc portion 72 which carries a proies g and roller assembly 73 that serves together una a Geneva gear member 'I4 to provide an intermediate drive which, as will hereinafter appea' serves to impart transitional movement to bull rings 3'? and 39 at the top and bottom of the platform or flight supporting column. Geneva gear member 'iii has four radial guide- Ways with which the pin and roller assembly is adapted'to cooperate and in this manner the Geneva member 74 will be turned one quarter of a revolution upon each full and complete revolution of the disc portion T2 of the intermediate gear 65. In this arrangement the Geneva gear member M is shown as formed upon a sleeve 'i5 which carries a beveled gear 'le at its other end. This beveled gear serves to drive two oppositely disposed and small spur gears l'! and "L3 that are respectively keyed to the verticaliy extending shafts 53 and i5 upon which the hull ring driving gears 42 and M are mounted. The beveled spur gears TI and 'IS and the shafts @-3 and are here shown'as journaled within a gear housing 'i5 which is supported upon a hori- With the various driving alignments in the positions shown, the pin and roller assembly I'I being on dead center, the dog or abutment pintle 35 will be in its uppermost position at the top of the sprocket It and as shown in Figure 8 of the drawings the dog or abutment 34 carried by the platform supporting bracket will be in substantial alignment with the pintle 35 At this time the transitional movement of the bull ring and the extending rails 3@ will be midway between their limits of transitional movement from one to the other side of the column.

It is believed that the operation of my improved parking facility will be understood from the above, but by way of over all consideration, and with reference to Figure 2 of the drawings, it may be explained that after an automobile has been driven upon the platform I9, with the electric motor 61 de-energized, the platform 22 at the top of the column will have moved around the sprocket I6 to a point where its rollers 3| will engage with the upper ends of the rails 33. At this time the platform I9 will be fully supported by two of the upwardly extending rails 38 carried by the bull ring 39. Now when thc motor 61 is energized the sprockets It and l? will turn in a clock-wise direction and thus cause the chain to move and carry the platforms I9, 2t and 2| upwardly along one side of the column while the platforms 22, 23 and 24 will descend along the other side of the column. When the platform 2| which is next in line reaches its uppermost point of travel, the Geneva gear drive will come into operation and cause the bull ring El to rotate through an angle of 180 and thus move the platform 2| over and into the position where the platform 22 is now shown. At the same time, as the platform 24 reaches its lower limit of travel the Geneva gear driving mechanism will also operate to carry this platform Eri around the column and into the position where the platform I9 is now located. In this manner it will be seen that the platforms will be moved in a substantially continuous manner up one side of the column formed by the members IB and II and downwardly along the other side thereof. When an automobile is being placed upon the platforms the motor el will be stopped to permit this loading and/or unloading as the platforms reach the bottom of the column. The unloading may take place when the platforms have reached the lower limit of their downward movement at the descending side of the column or at the point where the platforms at the other side of the column are in a position to assume their upward travel. It is contemplated that the electric motor will be provided with an automatic electrical control circuit with various limit switches and/or other automatic relays by which the movements of the platforms may be controlled in an entirely automatic manner.

While I have, for the sake of clearness and in order to disclose the invention so that the same can be readily understood, described and illustrated specific devices and arrangements, I desire to have it understood that this invention is not limited to the specific means disclosed, but may be embodied in other forms that will suggest themselves to persons skilled in the art. It is believed that this invention is new and all such changes as come within the scope of the appended claims are to be considered as part of this invention.
